public int GetResultStatus(string username, string password, int resultsId)
Checks the current progress of a cleansed data file generation after purchasing.
After the caller has requested to purchase a cleansed data file using the PurchaseResults
method, the system may take some time to generate the cleansed data file. The amount of time may vary between a few seconds for simple cases
to several minutes where some of the data cleansing tasks have to be re-processed in order to produce the requested results.
